Cavus Foot Deformity
A cavus foot or high-arched foot refers to a condition that can vary from a slightly high arch to a severe foot deformity. Cavus foot can lead to symptoms such as pain and instability. The condition may be inherited or associated with neurological disorders or other conditions.
Cavus foot reconstruction is performed to reduce pain and increase stability in the foot. It is indicated when conservative treatments including orthotics, shoe modifications, and bracing does not resolve the symptoms.
Cavus foot reconstruction involves various surgical techniques.
- Soft tissue surgery is often required, and can include:
- Tendon releases in the case of over pull from the muscles;
- Tendon transfers to correct deforming forces on the foot and ankle joints;
- Achilles tendon or calf muscle lengthening; and
- Release of a tight plantar fascia, a fibrous band that runs along the bottom of the foot.
- Osteotomies (bone cuts) of the heel bone or 1st metatarsal bone in order to re-align the foot.
- Joint fusions in the case of severe joint deformities and pain.
- Toe surgery - cavus feet are often associated with clawing of the toes. Painful claw toes can be surgically corrected, which may involve, tendon transfers, joint releases and joint fusions.
- Recovery following cavus foot reconstruction usually involves approximately 6 weeks non-weightbearing in a cast for the bones and tendons to heal, and final recovery may not be seen until 6 to 12 months after surgery.
